| j1939 21 download: Data Acquisition from HD Vehicles Using J1939 CAN Bus Richard Walter, Eric Walter, 2016-07-14 Modern vehicles have electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (or simply ‘controllers’) are networked together to share information, and output directly measured and calculated data to each other. This in-vehicle network is a data goldmine for improved maintenance, measuring vehicle performance and its subsystems, fleet management, warranty and legal issues, reliability, durability, and accident reconstruction. The focus of Data Acquisition from HD Vehicles Using J1939 CAN Bus is to guide the reader on how to acquire and correctly interpret data from the in-vehicle network of heavy-duty (HD) vehicles. The reader will learn how to convert messages to scaled engineering parameters, and how to determine the available parameters on HD vehicles, along with their accuracy and update rate. Written by two specialists in this field, Richard (Rick) P. Walter and Eric P. Walter, principals at HEM Data, located in the United States, the book provides a unique road map for the data acquisition user. The authors give a clear and concise description of the CAN protocol plus a review of all 19 parts of the SAE International J1939 standard family. Pertinent standards are illuminated with tables, graphs and examples. Practical applications covered are calculating fuel economy, duty cycle analysis, and capturing intermittent faults. A comparison is made of various diagnostic approaches including OBD-II, HD-OBD and World Wide Harmonized (WWH) OBD. Data Acquisition from HD Vehicles Using J1939 CAN Bus is a must-have reference for those interested to acquire data effectively from the SAE J1939 equipped vehicles. |

| j1939 21 download: Embedded Networking with CAN and CANopen Olaf Pfeiffer, Andrew Ayre, Christian Keydel, 2008 CAN (Controller Area Network) is a serial communication protocol that was originally developed for the automobile industry. CAN is far superior to conventional serial technologies such as RS232 in regards to functionality and reliability and yet CAN implementations are more cost effective. CANopen, a higher layer protocol based on CAN, provides the means to apply the ingenious CAN features to a variety of industrial-strength applications. Many users, for example in the field of medical engineering, opted for CANopen because they have to meet particularly stringent safety requirements. Similar requirements had to be considered by manufacturers of other equipment with very high safety or reliability requirements (e.g. robots, lifts and transportation systems). Providing a detailed look at both CAN and CANopen, this book examines those technologies in the context of embedded networks. There is an overview of general embedded networking and an introduction to the primary functionality provided by CANopen. Everything one needs to know to configure and operate a CANopen network using off-the-shelf components is described, along with details for those designers who want to build their own CANopen nodes. The wide variety of applications for CAN and CANopen is discussed, and instructions in developing embedded networks based on the protocol are included. In addition, references and examples using MicroCANopen, PCANopen Magic, and Vector's high-end development tools are provided. |

| j1939 21 download: A Comprehensible Guide to Servo Motor Sizing Wilfried Voss, 2007-08 The Importance of servo motor sizing should not be underestimated. Proper motor sizing will not only result in significant cost savings by saving energy, reducing purchasing and operating costs, reducing downtime, etc.; it also helps the engineer to design better motion control systems. However, the knowledge of mechanical systems and their influence on motor speed, inertia and torque requirements seems to decline in a world where modern technology aspects, such as tuning and programming, seem to be the main focus. The motor sizing process involves a number of mathematical equations, which are most certainly documented, but not necessarily with the motor sizing process in mind. This book focuses primarily on servo motor sizing and it documents in detail the inertia and torque calculations of standard mechanical components and the motor selection process. |

| j1939 21 download: Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles National Research Council, Transportation Research Board, Division on Engineering and Physical Sciences, Board on Energy and Environmental Systems, Committee to Assess Fuel Economy Technologies for Medium- and Heavy-Duty Vehicles, 2010-07-30 Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame. |

| j1939 21 download: Data Link Layer Truck Bus Control and Communications Network Committee, 2006 The SAE J1939 documents are intended for light, medium, andheavy-duty vehicles used on or off road as well as appropriatestationary applications which use vehicle derived components (e.g.generator sets). Vehicles of interest include, but are not limitedto, on- and off-highway trucks and their trailers, constructionequipment, and agricultural equipment and implements.The purpose of these documents is to provide an openinterconnect system for electronic systems. It is the intention ofthese documents to allow Electronic Control Units to communicatewith each other by providing a standard architecture.This particular document, SAE J1939-21, describes the data linklayer using the CAN protocol with 29-bit Identifiers. For SAE J1939no alternative data link layers are permitted.This SAE Recommended Practice revision incorporates changes tothe assigned SAE Reserved Bit to be the Extended Data Page Bit,Acknowledgement sections, the new proprietary A2 PGN (PGN 126720)and includes new SPN assignments in Appendix D.The 'Reserved' bit of the 29-bit of J1939 header hasbeen defined as the 'Extended Data Page' (EDP) bit. TheJ1939 Subcommittee has concerns there might be existing anddeveloping components for J1939 that don't verify theReserved/EDP bit is zero (0) before processing the 29-bit headerper the J1939-21 structure. It is important that existing andfuture J1939 applications examine the values of the EDP and DP bitsbefore interpreting the remaining 24 bits per the PDU Format (PF).PDU Specific (PS), and Source Address (SA) structure specified inJ1939-21.Backward compatibility is maintained during this change byspecifying the Extended Data Page bit value of zero for allexisitng J1939 PGNs. Prior to this functional change, J1939-21required the Reserved bit to be set to zero (0) in all J1939 PGNData Frame headers. |
| j1939 21 download: Compliance Truck Bus Control and Communications Network Committee, 2015 SAE J1939-82 Compliance describes the compliance tests and procedures to verify an SAE J1939 ECU will operate correctly on a SAE J1939 network. The purpose of these compliance procedures is to generate one or more test documents that outline the tests needed to assure that an ECU that is designed to operate as a node on a SAE J1939 network would do so correctly. SAE does not certify devices and these tests and their results do not constitute endorsement by SAE of any particular device. These tests are presented to allow testing of a device to determine self-compliance by the manufacturer of a device. The manufacturer can use its record of what procedures were run successfully to show the level of compliance with SAE J1939. This document has been revised to include new tests for recent changes to associated SAE J1939 documents, update cross references to the document section in the associated SAE J1939 documents, and add clarification to the test descriptions. The new tests have been added to cover changes made recently to the SAE J1939-21, SAE J1939-31, and SAE J1939-81 documents. Test descriptions and test names have been update for many of the tests associated with the SAE J1939-21 and SAE J1939-31 documents primarily for clarification. The tests listed in Tables A5, A6, A7, and A8 were reordered to keep together existing and new tests for similar aspects. |
